The absence of keratinized gingiva alone is not an indication for a periodontal surgical procedure. However, if recession increases during orthodontic treatment, then a gingival graft may be indicated. Orthodontic therapy and removal of a mandibular incisor where excessive gingival recession is present may be the indicated treatment.
